Hair System Leave-In Conditioner: Can You Use One?

Updated 3 November 2026

Yes, you can use a leave-in conditioner on a hair system, and most hair systems need one. The hair on a system gets no natural oil from your scalp, so it dries out without regular conditioning. Pick a leave-in conditioner for hair systems that suits human or synthetic hair. Keep it away from the edges of the base.

Cochrane & Co has fitted over 10,000 hair systems since 1996, from our salon at 37 Lambs Conduit Street, Holborn, London WC1N 3NG. We sell NAK sulphate-free shampoos and conditioners in the salon. Owner Paul Cochrane and our team can show you a home care routine. Here is what we tell clients about leave-in conditioner.

What Does a Leave-In Conditioner Do for a Hair System?

Your hair system cannot produce sebum (the natural oil that glands in your scalp make to keep hair moist). That is why a regular conditioning routine matters. After washing your hair system, apply a conditioner made for use with hair systems. We advise shampoos and conditioners without sulphate.

Can you use a leave-in conditioner for hair systems? Yes, you can. A good leave-in conditioner keeps the hair free of tangles. It is made to strengthen and hydrate the hairs, which keeps the system shiny and soft.

Whereas an everyday conditioner has to be rinsed off, a leave-in conditioner is applied after the wash and left in the hair system. Don’t leave in a regular conditioner though as this could cause hair strands to be damaged by the thick and creamy consistency.

Leave-in conditioners usually come in a spray or pump bottle. Some are made for human hair systems and some for synthetic ones, so check you have the right conditioner for your hair system type. If you are not sure which hair you wear, ask us at your next appointment.

Which Types of Leave-In Conditioner Suit Hair Systems?

There are leave-in conditioners that are compatible with every hair system. Some contain aloe and hydrolysed silk that increases hair flexibility and also provides sunscreen protector. Others are included within with a full moisturising kit for natural hair systems providing shampoo, conditioner and a UV protecting leave-in conditioner spray.

Additional UV protection will also stop oxidation of your system which may cause the colour to dull over a period of time.

How Do You Use a Leave-In Conditioner on a Hair System?

You’ll get the best results if you apply immediately after cleaning your hair system. Apply the conditioner evenly and use your fingers or a wide-toothed comb to spread the product.

If you need an extra boost you can use the leave-in conditioner by spraying a light mist to keep your system looking fresh between cleans. Remember to use it on your hair and not your scalp. Conditioning your hair system maintains shine, the perfect moisture content, and provides a soft and natural look.

Tips for Conditioning and Caring for Your Hair System

If you are wearing your hair system while you condition it, keep the product away from the edges. Conditioner there can loosen the bond and cause early detachment. That is one reason we suggest a salon Refit & Style every 12 weeks. We remove, clean, condition and refit the system, then cut and style your natural hair.

  • Apply conditioner through the hair from the root to the tip
  • Gently comb through with a wide-toothed comb to ensure the conditioner is evenly distributed
  • By using a high-quality leave-in conditioner you’ll ensure the longevity of your hair replacement system
  • Leave-in conditioners prevent damage as combs or brushes simply glide through the hair
